Parts from the appearance of the structure, its appearance complex and difficult process, so the selection of parts is casting.The parts are cast parts. In the processing, it is easier to ensure the processing accuracy of plane than the hole. So the parts main planes are hole, two blades of the Plectrum and groove. Therefore, in the design, it adopts the principle of plane first and hole second and divides the hole and planes working into extensive and intensive processing stages so as to ensure the accuracy. In this design, firstly, it uses the plane to work a datum; secondly, it uses the datum to work according hole. And in the latter process of working, it also takes hole as the poisoning base and works the two bales of Plectrum, hole, bottom plane, groove and inclined plane. In the entire machining process, it uses separately the milling machine, driller and boring machine. And the design aspect of milling, boring and milling ducts special fixture. They also have adopted the positioning of a two marketing positioning. According to the requirement, it designs the special fixture. For the size of parts is not very big, it doesnt require strong clamping force. Therefore, methods of clamping are manual clamping; that is because it is simple and the design is more convenient to meet the requirements of clamping.
